Imaging and Signals Intelligence Space Systems

The major effort within the US satellite reconnaissance program in the 1960s and 1970s featured overhead visual imaging systems, which produced information not obtainable any other way. (CORONA, GAMBIT, and HEXAGON, the early filmbased satellite systems, have already been well documented.) But there were important intelligence questions that could not be answered with pictures alone. The first question involved determining the location and characteristics of Soviet radars that could detect American strategic bombers. The second involved the performance capabilities of Soviet missiles—ICBMs and ABM systems. These two problems led the list of reasons favoring SIGINT satellites that could listen to and record the signals of Soviet radars, radio communications, and telemetry systems.

Russia Jams GPS In The Baltic States: Researchers Locate Signal Sources Near Kaliningrad

Polish researchers have finally told the world where Russia is wreaking havoc in the skies and at sea in the Baltic region. Using a network of monitoring stations, they have tracked down the locations of satellite navigation jamming (GNSS) and pointed the finger at Kaliningrad and the St Petersburg area. The resourceful military uses both signal jamming and spoofing, a more sophisticated technique of coordinate spoofing that can make aircraft or ships think they are in a different location on the map altogether.
